Merge tag 'wireless-drivers-next-2021-02-12' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next Kalle Valo says: ==================== wireless-drivers-next patches for v5.12 Second set of patches for v5.12. Last time there was a smaller pull request so unsurprisingly this time we have a big one. mt76 has new hardware support and lots of new features, iwlwifi getting new features and rtw88 got NAPI support. And the usual cleanups and fixes all over. Major changes: ath10k * support setting SAR limits via nl80211 rtw88 * support 8821 RFE type2 devices * NAPI support iwlwifi * add new FW API support * support for new So devices * support for RF interference mitigation (RFI) * support for PNVM (Platform Non-Volatile Memory, a firmware data file) from BIOS mt76 * add new mt7921e driver * 802.11 encap offload support * support for multiple pcie gen1 host interfaces on 7915 * 7915 testmode support * 7915 txbf support brcmfmac * support for CQM RSSI notifications wil6210 * support for extended DMG MCS 12.1 rate ==================== Signed-off-by:

As udp_port_cfg struct changes its members with dependency on IPv6 configuration, the code in rxrpc should also check for IPv6. Fixes: 1a9b86c9 ("rxrpc: use udp tunnel APIs instead of open code in rxrpc_open_socket") Reported-by:

Mat Martineau says: ==================== mptcp: Add genl events for connection info This series from the MPTCP tree adds genl multicast events that are important for implementing a userspace path manager. In MPTCP, a path manager is responsible for adding or removing additional subflows on each MPTCP connection. The in-kernel path manager (already part of the kernel) is a better fit for many server use cases, but the additional flexibility of userspace path managers is often useful for client devices. Patches 1, 2, 4, 5, and 6 do some refactoring to streamline the netlink event implementation in the final patch. Patch 3 improves the timeliness of subflow destruction to ensure the 'subflow closed' event will be sent soon enough. Patch 7 allows use of the GENL_UNS_ADMIN_PERM flag on genl mcast groups to mandate CAP_NET_ADMIN, which is important to protect token information in the MPTCP events. This is a genetlink change. Patch 8 adds the MPTCP netlink events. ==================== Signed-off-by: -

Allow userspace (mptcpd) to subscribe to mptcp genl multicast events. This implementation reuses the same event API as the mptcp kernel fork to ease integration of existing tools, e.g. mptcpd. Supported events include: 1. start and close of an mptcp connection 2. start and close of subflows (joins) 3. announce and withdrawals of addresses 4. subflow priority (backup/non-backup) change.

When remote side closes a subflow we should schedule the worker to dispose of the subflow in a timely manner. Otherwise, SF_CLOSED event won't be generated until the mptcp socket itself is closing or local side is closing another subflow. Signed-off-by:

Florian Westphal authored
Prepare for subflow close events: When mptcp connection is torn down its enough to send the mptcp socket close notification rather than a subflow close event for all of the subflows followed by the mptcp close event. This splits the helper: mptcp_close_ssk() will emit the close notification, __mptcp_close_ssk will not. Signed-off-by:

Mat Martineau says: ==================== mptcp: Selftest enhancement and fixes This is a collection of selftest updates from the MPTCP tree. Patch 1 uses additional 'ss' command line parameters and 'nstat' to improve output when certain MPTCP tests fail. Patches 2 & 3 fix a copy/paste error and some output formatting. Patch 4 makes sure tests still pass if certain connection-related packets are retransmitted. ==================== Signed-off-by: -

If we receive less MPCapable SYN or 3rd ACK than expected, we now mark the test as failed. On the other hand, if we receive more, we keep the warning but we add a hint that it is probably due to retransmissions and that's why we don't mark the test as failed.

Before we had this in case of SYN retransmissions: (...) # ns4 MPTCP -> ns2 (10.0.1.2:10034 ) MPTCP (duration 1201ms) [ OK ] # ns4 MPTCP -> ns2 (dead:beef:1::2:10035) MPTCP (duration 1242ms) [ OK ] # ns4 MPTCP -> ns2 (10.0.2.1:10036 ) MPTCP ns2-60143c00-cDZWo4 SYNRX: MPTCP -> MPTCP: expect 11, got # 13 # (duration 6221ms) [ OK ] # ns4 MPTCP -> ns2 (dead:beef:2::1:10037) MPTCP (duration 1427ms) [ OK ] # ns4 MPTCP -> ns3 (10.0.2.2:10038 ) MPTCP (duration 881ms) [ OK ] (...) Now we have: (...) # ns4 MPTCP -> ns2 (10.0.1.2:10034 ) MPTCP (duration 1201ms) [ OK ] # ns4 MPTCP -> ns2 (dead:beef:1::2:10035) MPTCP (duration 1242ms) [ OK ] # ns4 MPTCP -> ns2 (10.0.2.1:10036 ) MPTCP (duration 6221ms) [ OK ] WARN: SYNRX: expect 11, got 13 # ns4 MPTCP -> ns2 (dead:beef:2::1:10037) MPTCP (duration 1427ms) [ OK ] # ns4 MPTCP -> ns3 (10.0.2.2:10038 ) MPTCP (duration 881ms) [ OK ] (...) So we put everything on one line, keep the durations and "OK" aligned and removed duplicated info to short the warning. Signed-off-by:

Even if that may sound completely unlikely, the mptcp implementation is not perfect, yet. When the self-tests report an error we usually need more information of what the scripts currently report. iproute allow provides some additional goodies since a few releases, let's dump them. Signed-off-by:

Use napi to reduce overhead on rx interrupts. Driver used to interrupt kernel for every Rx packet, this could affect both system and network performance. NAPI is a mechanism that uses polling when processing huge amount of traffic, by doing this the number of interrupts can be decreased. Network performance can also benefit from this patch. Since TCP connection is bidirectional and acks are required for every several packets. These ack packets occupie the PCI bus bandwidth and could lead to performance degradation. When napi is used, GRO receive is enabled by default in the mac80211 stack. So mac80211 won't pass every RX TCP packets to the kernel TCP network stack immediately. Instead an aggregated large length TCP packet will be delivered. This reduces the tx acks sent and gains rx performance. After the patch, the Rx throughput increases about 25Mbps in 11ac.

Register rrsr determines the response rate we send. In field tests, using rate higher than current tx rate could lead to difficulty for the receiving end to receive management/control frames. Calculate current modulation level by tx rate then cross out rate higher than those. Signed-off-by:

We use this driver as a backport that also runs on older kernels (as part of the backports project). So we use some checks to backport or prevent code from compiling in incompatible kernel version. When I took one of the PNVM patches from the backport, I accidentally left the comment that a certain part of the code doesn't work in older kernels. This obviously should never be valid for the mainline. Remove this comment. Reported-by:
